Perceptually Maximized Light Ray Synthesis with Only Two-Layered Light Field Display

Multilayer light field three-dimensional displays are becoming popular due to their full resolution reconstruction and easy fabrication by utilizing existing display technologies such as liquid crystal display (LCD) panels. However, these displays still suffer from limited performance, achieving low angular resolution, narrow field of view, and small depth of field. One of the recent research ideas focusing on overcoming these limitations is perceptual quality improvement. But, currently introduced methods consider only specific issues/applications such as moire fringe effect, and near-eye display technology. In this work, the authors propose a novel method of approximating light field data for dual-layered light field display considering the Human Visual and Perceptual System. The authors' display configuration includes two liquid crystal panels with uniform backlight with no time multiplexing. It is not necessary for LCD panels to be parallel. For a wide field of view configuration, the authors introduce a quadratic penalization term to reduce ghost effects caused by neighboring views. This leads to an improved perceptual approximation of a given light field and increases the possibility of usage in design with a wider field of view configuration.
